According to a report in The Washington Post on Friday, Pichai met "a group of civilian and military leaders mostly from the office of the Under Secretary of Defence for Intelligence, the Defence Department directorate that oversees the Artificial Intelligence (AI) drone system known as 'Project Maven'".

Google did not make any comment on this report. After facing backlash over its involvement in the Pentagon project "Maven", Pichai in June emphasised that the company will not work on technologies that cause or are likely to cause overall harm.

Following the anger, Google decided not to renew the project with the US Defence Department after it expires in 2019.

"We will not design or deploy AI in weapons or other technologies whose principal purpose or implementation is to cause or directly facilitate injury to people," Pichai had said.

We will not pursue AI in "technologies that gather or use information for surveillance violating internationally accepted norms," the Indian-born CEO added.

Pichai noted that "while we are not developing AI for use in weapons, we will continue our work with governments and the military in many other areas like cybersecurity, training, military recruitment, veterans' healthcare, and search and rescue".

Pichai last week met Republican lawmakers and agreed to testify before the House Judiciary Committee in November to allay concerns over privacy issues and the tech giant's entry into the Chinese market.
